Given that the universal set is all real numbers and set s is defined as the set of all x such that x is less than 5, which of the following is the complement of s? s = {x | x < 5}

never the less a short version would be the correct answer being D.

i would you but i don't under stand the qustion

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
